Title: Improvements in and relating to multiple unit electric control
IPC: B60L15/34
Filed: 1926-09-03
Abstract: 281,398. British Thomson-Houston Co., Ltd., and Sarjeant, C. J. Sept. 3, 1926. Governors, applications of; relay or power apparatus.-Diesel engines or other prime movers in one or several coaches of a train can be controlled at any of several points of the train, each prime mover having a governor adjusted by an electric motor which is controlled by a master controller provided at each control point. The master controllers 1 are interconnected by train wires 4 to each electric controlling motor 2 which act e.g. on a pivoted lever to compress a synchronizing spring on each governor to control the prime mover. The electric motors 2 are connected in parallel, and to cause them to move through equal or corresponding distances they are provided with mechanically coupled dial switches 3 while the positions of the master controllers 1 are electrically interlocked with the corresponding positions of the dial switches. As soon as a motor has driven its dial switch to a position corresponding to that of the master controller the dial switch 3 causes the circuit of the motor to be interrupted, thus bringing the motor to rest. Each master controller has the usual dead man's handle 5, which automatically interrupts the motor circuit and applies the brakes. The master controllers 1 are also provided with segments 6 to interrupt the control circuit of the exciter fields of the generators (not shown) supplying power to the motors in the off position of the controller so that the supply is taken from the driving motors when the controller is in the off position. Double field contacts 7 on the main shaft of each controller, control the coil circuits of contactors 8 and 9, which in turn control the coil circuits of contactors 10, 11 respectively through the contacts of dial switch 3 and master controller 1. Contactors 10, 11 control the two field windings 12, 13 of motor 2, one for each direction of rotation. Limit switches 14 are provided at the ends of travel of the dial switches to prevent the motors from overrunning. Each controller 1 has an additional small two-position removable handle, removable when the main controller handle is in the off position, and the main handle can only be raised from the off position when this small handle is in the other position. When the lever compressing the governor spring reaches the position of minimum compression, the limit switch 14 opens, to interrupt the motor circuit and the contactor 16 circuit, thus giving minimum governor spring compression for starting up.
Patent GB-387367-A (GB)
Title: Improvements in tacheometers in which centrifugal action creates fluid pressure
IPC: G01P3/20
Filed: 1931-07-30
Abstract: 387,367. Centrifugal speedometers. PRECISION MODERNE, 162, Rue St- Charles, Paris. July 30, 1931, No. 21759. Convention date, Aug. 11, 1930. [Class 106 (iii).] A speedometer comprises means for transforming centrifugal forces, which arise from a rotating shaft the speed of which is required, into a fluid pressure in a closed integral pressure receiving and indicating system completely filled with liquid. The rotating masses 3, 3<1> give rise to centrifugal forces F, Fl which act through the bell-crank levers 4, 4<1> on the sleeve 6 sliding along the rotating shaft 1. The sleeve 6 acts through the ball 20 on the movable end 7 of a metallic bellows 8 with a fixed end at 9 to a hole in which is soldered or welded a capillary tube 10 transferring the pressure of the liquid in the bellows 8 to a manometer 11 of the closed chamber type such as a Bourdon gauge. By the above means the speed can be indicated at a distance and, according to the Specification as open to inspection under Sect. 91, at several points by having a number of manometers connected to the tube 10. The fluid contained in the bellows 8 may be very fluid and uncongealable for apparatus which has to give rapid indications of changes of speed and has to operate at a low temperature, or the fluid may be very viscous in cases in which the variations in speed of the member under consideration would produce objectionable oscillations of the pointer of the manometer. In Fig. 2 is shown a modified construction for measuring the speed of a low-speed machine driving the shaft 1 which, through the speed multiplying worm gearing 12, 13, rotates the friction disc 14 loose on shaft 21 to drive the friction disc 15 rigid with shaft 21. An inclined ring 22 is pivoted on the shaft 21 and is connected by a link 23 to a sliding member 6 actuating the movable end 7 of the metal bellows 8 mounted in a casing 18. The apparatus is contained in a casing 19 having oil in the lower part ensuring continuous lubrication of the worm gearing and splash lubrication of the sliding parts 14, 15 which reduce inertia stresses in the driving members when sudden variations in speed occur. In modifications the centrifugal arrangement of Fig. 1 may be fitted to the apparatus of Fig. 2 and vice versa. If desired a plurality of centrifugal masses may be employed. The liquid chamber may be formed by a capsule or other simular member provided this member is not sufficiently stiff to give false values under the action of variations in volume due to differences in temperature. The type of chamber shown in Fig. 1 may be fitted to the apparatus shown in Fig. 2, and vice versa.

Abstract: 1300342 Measuring fluid-flow-rate DANIEL INDUSTRIES Inc 19 April 1971 [4 Feb 1971] 21763/71 Heading G1N In a flowmeter of the type in which fluid-flowrate is measured by measuring the pressure drop across an orifice plate 13, the gain and zero points of an amplifier 18 are automatically selected according to the range in which the measured signal lies. As shown, when the signal on lines 20, 22 is below a level set by variable resistor 70, transistor 49 conducts and relays 52, 56 are energized to select gain and zero resistors 33, 35 for amplifier 18. Transistor 60 conducts and transistor 66 is blocked. When the signal at 20, 22 exceeds the level, transistor 49 becomes blocked, de-energizing the relays and selecting resistors 32, 34. Transistor 60 also becomes blocked whereupon transistor 66 conducts to alter the reference level on 72 to introduce hysteresis.
